SPINNINGQFRAME.

ToV Acil-Z whom t may concern." 1-

Be it known that I, ALBERT H." MoRToN,

a citizen of the United States,y residing at Lowell, in the county of` Middlesex and State of `Massachusetts, have invented certain new and useful-Improvements in Spinning-F rames; andl do hereby declare the following to be Va full, clear, and exact description of the invention, such as will envablefothers skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in spinning frames. rPhe object of the invention is to inipi'ove'the construction of the thread guide, thread board, dofling rail and associated parts and, to this end,

the invention consists in the improvements hereinafter described and particularly point- 'ed out in the claims. l

In the accompanying drawings illustrating the invention Figure l is a plan of the doli'ing rail of the spinning frame showing l the thread boards attached thereto and i kerf end of the shank 1s threaded and receives a showing their relative position to the roll Vbosses of the drawing rolls; Fig. 2 is a bottoni plan of one of the thread boards and thread board supports; Fig. 3 is a longitudinal sectional elevation of the same; Fig. t is a perspective View of a portion of the shank of the thread guide. i

The thread guide, which is of the kind known as a vibrating thread guide, not vbecause it vibrates but because the thread vibrates in it has a D-shaped guide passage, the long straight side of which aiords ample surface for wear, thereby preventing grooving of the guide. The shank 2 of this thread guide isreceiv'ed in a hole in the boss on the underside of the thread board 3. The

shank 2 of the guide is provided with a projecting iin 4 which is received in a saw 5 formed in the front of the boss. The

nut. kThe iin 4 holds the shank from turning in the boss 6 and affords a shoulder against which the nut xedly and non-adustaloly holds the thread guide'. The thread board 3 is pivotally mounted upon the front end of the threadlooard support 7, in turn vsecured to *the doiing rail .8 by means of the bolt 10. The thread board support 7 is slotted at 11 so that it may be adjusted longitudinally and laterally.

The thread guides l are each located with the center of the straight surface of the D- shaped guide passage over the center of the j Speeication of Letters Patent.

spinning-spindles 12. The drawing rolls 13 discharge the roving or yarn or thread near the centers of their bosses and from this point the thread rims to the thread guide.

The' thread board supports are secured to the dofling rails not opposite the centers o'l the roll bosses nor opposite the spindles but at a point on the 'projection of the line of the thread on the doiing rail. By this means, when the thread guide is brought to -a' position directly over its spindle the straight surface of the D-shaped thread passage is at right anglesto the direction of travel of the thread soy that as the thread vibrates inthe thread guide its wear on the thread guide is distributed over the whole or the larger part of the straight surface of the thread passage.

The construction above described has important advantages over prior existing eonstructions which are apparent to those skilled in the ait. It is desired to point out, in this connection, that when the thread guide is brought to proper position with respect to its spindle it presents its flat side normally to the line of the thread and that this adjustment is secured by loosening one screw, which afl'ords provision both for the longitudinal and lateral adjustment of the thread guide. The thread guide occupies a definite and fixed position with relation to the body of the thread board and is nonadjustable with relation thereto. It is within the scope of the invention, viewed in this aspect, that the thread board and thread guide should be integral. Also that while the spindles are equally spaced, as usual, and the roll bosses are arranged as usual, in pairs, and with the usual spacing and separation for the bearing supports of the roll standards, the thread guides are all properly positioned with respect to the spindles.

Having thus described the invention, what is claimed is:

l. A spinning framehaving, in combination, drawing rolls, equally spaced spindles throughout the length of the spinning frame, a doffing rail and thread boards sup ported to turn on the doling rail, the center oit'- the swing of the thread boards lying under the line of the thread leading from the rolls to the spindles.

2. A spinning frame having, in combination, drawing rolls, spindles, a doiling rail, thread boards carried by the doiing rail,

thread guides carried by the thread boards and ixedly connected therewith, said thread boards being connected to the clotting rail so as to pern'iit of longitudinal andturning adjustment. 3. A spinning frame having, in combination, drawing` rolls, spindles, a doffng rail, thread boards supported on thedofling rail, thread guides Carried by the thread boards, said thread guides beingfixed With relation to the thread boardsl and said thread boards Y being seeured to the `clotting rail by ,fastening means permitting longitudinal and turning` adjustment of the thread guides toposition them correctly With relation to the spindles irrespective of the position of attaehinent to the doliing rail.

4. ,A spinning fraine having, in combination, drawing rolls, spindles, a. dofling rail,

athread board supported by the doliing` rail,

tion, drawing rolls, spindles, a doiing rail Y -andthread boards supported on the dolling,- rail with their center lines oblique to the with the line of thread leading from the rolls to the spindle. i Y
